Eleven members of the Middle School Math Club each paid the same amount for a guest speaker to talk about problem solving at the

Ilia_Sergeevich [38]

The correct answer for the question that is being presented above is this one: "The missing digit is 3."

The missing digit is represented by A ⇒ $1A2, where A represents a whole number from 0 to 9.

Try substituting any number from 0 to 9 for A (the middle digit or tens place) , then divide by 11 members.

Option 2: A = 3 ⇒ $1 3 2
$ 132 ÷ 11 = $12

The only one-digit that gives a whole number quotient when it takes the place of tens digit in $1 __2 is 3. Because $ 132 ÷ 11 = $ 12. (Option 2)

The missing digit is 3.

Quinn has 6 bottles of water that each weigh 3/5 pound. What is the total weight of the water bottles? Use the number line to he

olganol [36]

Answer:

The weight of 6 bottles = $3\frac{3}{5}\ pounds$ or $3.6\ pounds$

Step-by-step explanation:

Given:

Total number of bottles = 6

Weight of each bottle = $\frac{3}{5}$ pound

To find the total weight of 6 bottles.

Solution:

We can plot the number line for six bottles.

We can the plot the weights in another number line.

Each unit represents $\frac{3}{5}$ pound of weight.

As the number of bottles increase the number of pounds of weight increase by $\frac{3}{5}$ .

Thus, weight of 6 bottles = $\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}$ $=\frac{18}{5}$ pounds

Converting fraction to mixed number.

$\frac{18}{5}=3\frac{3}{5}$ pounds

Or in decimals $\frac{18}{5}=3.6\ pounds$

Thus weight of 6 bottles = $3\frac{3}{5}\ pounds$ or $3.6\ pounds$

What is the square root of -1

Romashka [77]

Answer:

Step-by-step explanation:

Now, before you think I'm just stealing points, let me explain. The square root of a number is the number that, if you multiply it by itself, it equals that number. The square root of 4 is 2, because 2 * 2 = 4.

Also, a negative number times another negative number, is a positive number. -2 * -2 = 4

With both of those true, then what number could be multiplied by itself to equal a negative number? i.

i is a weird number that I don't really know how to explain all that well. I am sorry, but that is all that I can give you. i is very complex and has various different equivalents, and different meanings, but i is equal to $\sqrt{-1}$ .

Hope that this helps!
